[promotion] Why a newsletter?

I don't know why, but recently 1) my traffic has increased a lot and perhaps related to that 2) I've gotten requests for a newsletter. I already supply my RSS feeds via email as a subscription option using Feedburner, but I gather this is not what is being asked for.

So..my questions for those of you nice people who have a separate newsletter that is not just taking a feed or something of your blog posts -

• - what are the the advantages of having a separate newsletter? Does it bring more visitors/fame/fortune/karma?
• - What do you put there that you don't put in your posts?
• - how frequently do you send out your newsletter?
• - do you put a copy of your newsletter on your site for non-subscribers to access?
